[FUGSPBR] Problema com tape

[Fabiano Caixeta Duarte]

Salve!

Estou tentando fazer um backup em fita e segui as instruções do handbook
sobre como usar uma fita pela primeira vez.

No teste sugerido de fazer um primeiro dump deveria dar o erro
DUMP: End of tape detected

Está dando o seguinte erro:

#dump -f /dev/sa0 -L /
  DUMP: Date of this level 0 dump: Wed Mar 31 10:46:30 2004
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping snapshot of /dev/da0s1a (/) to /dev/sa0
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 94731 tape blocks on 2.44 tape(s).
  DUMP: write error 10 blocks into volume 1
  DUMP: Do you want to restart?: ("yes" or "no")

E qq tentativa de escrita que faço na fita dá o seguinte erro:

#tar cf /dev/sa0 /etc/
tar: /dev/sa0: Cannot open: Input/output error
tar: Error is not recoverable: exiting now

Parte relevante do dmesg:

Alguém poderia me dar alguma idéia do que fazer?

Obrigado!
